Bumper Sensor Module
This module houses the infrared emitters and receivers that monitor bumper displacement. A failure in the phototransistor or excessive internal dust accumulation within the module can cause a permanent 'high' signal, leading the firmware to believe a collision is constantly occurring.

Bumper Faceplate Assembly
The physical polycarbonate bumper shell can become warped or its internal return springs can lose tension. This prevents the bumper from returning to the neutral 'open' position after a collision, mechanically keeping the sensors triggered and throwing Error 9.

Main Control Board
If the physical bumper and sensors are verified functional, the root cause often lies in the mainboard's logic circuit. A failed pull-up resistor or a damaged GPIO pin on the microprocessor can cause the system to misinterpret sensor input levels as a constant bumper press.
